Relatively few people, aside from radio "DXers" (people whom enjoy a pastime/hobby of pursuing long-distance radio reception by various signal-propagation means) know that FM broadcast radio stations, and also television broadcast stations, can "propagate" for extraordinary long-distances at certain times of the year and are not simply limited to "line-of-sight" reception.
This is particularly true during the DXer's local summertime period, when the ionesphere can become like a "mirror" to radio signals and reflect/refract FM broadcast stations, as well as VHF ham-radio and other VHF radio signals, quite long distances.
I have been an enthusiast of long-distance reception of broadcast radio of all types for over three decades.
These recordings are also quite wonderful "air-checks" of a multitude of FM radio stations across western and central Canada, the USA, and northern Mexico.
Even more amazing (to me) is a recording by Dave Headland (of Victoria, Australia - refer the MP3-file with the words "Cook Islands" in it) whom traveled to the Cook Islands in July 1989 where he recorded astounding reception of 95.1 KAOI Maui, Hawaii (100 kw ERP). We believe this is not sporadic e-skip (Es), but a form of TE (trans-equatorial) skip, as the signal is very multi-pathy sounding, but clear enough to enjoy and understand!
As soon as I can locate Dave's FM DX tapes of FM Es DX from New Zealand to eastern Australia, I will convert them to MP3 files and upload those MP3 files here.
Enjoy the huge variety of DX and the variety of FM radio formats portrayed here.
